bpx-01 minocycline 1% topical gel for reduction of propionibacterium acnes

Conditions: Acne Vulgaris

Summary: this is a phase 2a study which is being conducted in healthy volunteers in order to evaluate the comparative reduction of propionibacterium acnes in-vivo following once daily topical administration of bpx-01 minocycline 1% topical gel (bpx-01) or bpx-01 vehicle control.

the objective of this study is to evaluate the comparative reduction of propionibacterium acnes (p. acnes) in-vivo following once daily topical administration of bpx-01 minocycline 1% topical gel or bpx-01 vehicle control gel. a secondary objective is to assess the tolerance of the treatment regimen versus a vehicle control. safety laboratory data (chemistry and hematology) and plasma levels of minocycline are also of significant interest to the sponsor. this is a single center, randomized, double blind, two-cell, vehicle controlled p. acnes study. all subjects will be randomized 2:1 to 1% bpx-01 or vehicle control to be applied as a topical gel once daily for four (4) weeks. this is a six (6) week study with a four (4) week treatment period and a two (2) week post treatment follow up visit. the clinical endpoint is in-vivo quantification of p.acnes. the safety/tolerance endpoints are; observer reported: erythema, scaling-peeling, edema, and subject reported: tightness, burning-stinging, and itching. plasma levels of minocycline and basic hematology and chemistry laboratory values will be collected.
